One wintry day a lonely stray cat wandered into the Royal Hotel. He chased mice so well that he was given the job of Hotel Cat. Tired of always spending time in the cellar Tom ventured upstairs and met the gentle Mrs. Wilkins, a longtime hotel resident who had the ability to communicate with cats. She encouraged Tom to keep an open mind about the hotel guests.
One night, during the winter of New York City's Big Freeze, Tom detected three cats in one of the rooms. It turned out that due to a boiler breakdown in his house, Captain Tinker had brought Jenny Linsky and her brothers Edward and Checkers to stay at the hotel until the boiler was fixed. Other homes experienced boiler breakdowns too and soon other members of the Cat Club could be found staying in rooms at the Royal Hotel. Before long, plans were underway for the Cat Club Stardust Ball, with the help of Tom, who had proved himself helpful and considerate after all. Soon he became a "friend for ever" of Jenny and her pals.
